A coin that pays small wallets invites one whale to become a hundred small wallets. That is the whole
design problem, and it is the reason the rule is published here in full rather than kept as a surprise.
Four gates, stacked — each one cheap to pass honestly and expensive to farm.
eb ≤ 1% of supply · 100 bps
The rich line
Hold more than a hundredth of the supply and you are on the other side of this story.
Everyone below the line is in the pool; everyone above it is who funds it.
eb = min(at snapshot, now, bought on pair)
What actually counts as yours
Three gates in one number. You must have held it at the snapshot, you must still hold it,
and you must have bought it on the pair rather than been handed it by another wallet. The
smallest of those three is what you are paid on.
snapshot = latest − 576000 − (hash mod 576000)
A snapshot nobody can time
It lands 12 to 24 hours in the past, and the offset comes from a block hash that did not
exist until the block did — so it cannot be positioned for in advance, and it can be
recomputed by anyone afterwards. The seed block and hash go in every payout record.
It also means nothing pays out for the first 12 to 24 hours
after launch: until a cohort has held that long, no wallet can clear the gate. Fees accrue and
go out in the first distribution that qualifies.
weight = eb ^ (1 − 0.3)
Smallest first
Shares run on eligible balance raised to a power below one, so a smaller wallet earns more
per token held while a larger one still earns more in total. The exponent is the whole
redistribution dial, and it is set at 0.3.
cap 5% of any one pot
A cap on the take
No wallet can pull more than a twentieth of a single pot. What the cap knocks back is
re-spread across everyone else, and anything that still cannot be placed is carried into the
next distribution — never dropped, never quietly kept.
not final
Locked before launch
These are the values the keeper runs today, and they are still being tuned. The final
numbers are published here before $ROBIN goes live, and any change after that is logged with
the block it took effect.
Here is the number most projects would hide. Splitting one bag across 100 wallets
multiplies a farmer’s weight by at most 3.98× — that is 100 raised to the
0.3 in the formula above. Their actual payout rises by less, because the pot is finite and shared,
and the ceiling is only approached by someone still small next to the honest pool.
That gain is arithmetic, not an oversight. Any rule more generous to small wallets
than a flat pro-rata split rewards splitting — that is what “progressive” means.
The only Sybil-proof setting is 0, and it buys that by paying everyone below the line strictly in
proportion to what they hold, which is no longer Robin Hood. We picked 0.3 and we are telling you
what 0.3 costs.
What the gates do instead is make each fake wallet expensive: it has to buy on the pair, which
means paying the fee that funds the pot it is farming, and it has to be sitting there before a
snapshot it could not see coming. Slow and costly, not impossible.
